IMPROVEMENT IN CHURNDASHERS.

Specification forming part of Letters Patent No. l 5 {,l52, dated May19, 1874; application led March 21, 1874.

To all whom it may concern:

Beit known that I, SAML. J. OLMsrED, of Binghamton, in the county ofBroome and State of New York, have invented certain new and usefulImprovements in OhurnDashers 5 and I do hereby declare the followingtobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification..

The nature of my invention relates to an improvement in churn-dashers;and it consists in the arrangement and combination of parts which willbe more fully described hereafter.

lhe accompanying drawings represent my invention.

A represents an ordinary churn-handle, to the lower end of which issecured the slotted frame c, made of any non-corrosive metal, and whichhas a hole made through its lower end, and a bearing for the end of thespindle d in its upper one. The dash e is made of a block of wood, orother suitable material, having its bottom made concave, so as to forman air-chamber, g,and having a number of inclined wings, i, projectingfrom its sides, which canse the dash to rapidly revolve in reversedirections as it is moved back and forth through the milk. Secured inthe top of the dash, and projecting up into' the frame o, is

the screw-spindle d, which is centered in position by having its upperend sharpened, so as to catch in the bearing in the frame, and which isprevented from coming out by the nut o. The spindle is threaded itsentire length, and is made long enough to leave a slight space betweenthe top of the dash and lower end ot' the frame, so that as the spindlewears away the nut can be screwed down so as to compensate for the loss.Each time that the dash is raised above the milk, a volume of air istaker into the chamber g, which, as the dash is forced downward throughthe milk or cream, is drawn out by the rotation of the wings, andmingled with the cream, thereby greatly assisting in breaking up theglobules which hold the butter.

Having claim- The combination oi the handle a', slotted frame c,adjustable spindle d, having a double bearing nut, o, and revolvingdashcr having an air-chamber formed in its under side, sub stantially asshown and described.

In testimony that I claim the foregoing I have hereunto set my hand this9th day of March, 1874.

thus described .my invention, I

SAMUEL J. OLMSTED.
